Making PDFs accessible means ensuring that people with visual, auditory, or cognitive disabilities can access the information within them. For many government and educational institutions, this isn't just a best practice—it's a legal requirement (often under Section 508 or ADA).
Key Components of an Accessible PDF
- Tagging: Tags provide the hidden structure that tells screen readers the difference between a header, a paragraph, and a list.
- Alt-Text for Images: Every meaningful image should have a text description for someone who cannot see it.
- Logical Reading Order: Ensure the screen reader moves through the document in the same order a sighted person would.
- Language Specification: Set the primary language of the document so the screen reader uses the correct pronunciation.
Tips for Better Accessibility
- Use Selectable Text: Never use a PDF that is just a large image of text. Use OCR to make it searchable and selectable.
- High Color Contrast: Ensure there's enough contrast between your text and background colors.
- Avoid "Click Here" Links: Use descriptive link text like "Download the Annual Report" instead.
- Header Hierarchy: Use proper nested headers (H1, H2, H3) rather than just bolding text.
